Ryloth: Mission 9 - Enemies of my Enemies

Following a series of cutscenes, you'll find yourself forced to defend a cavern from incoming swarms of droids. You can battle them all day if you like, slowly earning energy points, but that's not the method that you need to follow to succeed. Instead, you're going to need to close a series of gates to block your foes from ever arriving.

Collect the artifact along the back left corner before you bother with the terminals.

Solve more ring-based puzzles while under droid fire.

At the first position, there are two terminals along the right side of the screen. Ignore those for a moment and head toward the back left corner. There are some crates here, and behind those rests a barely visible artifact.

To hack the terminals and close the gates that are allowing enemies to arrive, you need to play the ring-turning mini-game again. It's no harder here than it is elsewhere, but now you're under fire. If you take a hit while attempting to solve the puzzle, you'll have to start fresh. Therefore, clear away the immediate vicinity, then quickly access the terminal by slashing at it with your lightsaber when the appropriate icon appears on-screen to indicate that you are near enough. Then solve the two terminal puzzles before too many enemies swarm you.

When you've solved those puzzles, the viewpoint will shift toward the left as new waves of enemies attack from that direction. Again, you'll need to clear away the rabble before solving two terminal puzzles. The first one is lower toward the ground. Solve it, then use your hover pack to reach the higher ledge where you should take a moment to clear away any nearby foes. When you get a break, use the terminal and swiftly solve the puzzle before more droids can arrive on the scene.

Explosives are a great way to tend with the vulture tank.

Fire from behind the low shelter during the mini-game to quickly slay swarms of weak droids.

Once those two gates are closed, a new enemy will arrive as the viewing angle shifts gradually toward the right again. This is one of the vulture droids, so you'll find as usual that it can withstand a great deal of damage from your blasters. Aim for its top pod with your explosives to make quick work of the over-sized mech.

Once you've done so, a beacon will appear. Stand over it and press the button indicated on-screen to access a mini-game. Here, the goal is to destroy as many enemy droids as possible within the 45 seconds allotted you. The easiest way to do that is to duck around behind the low shelter that runs along the center of the screen. Press up against it but don't crouch. Instead, run back and forth firing shots that sweep left, right, then left again and so forth. You can pause once in awhile if too many enemies gather in a cluster, since that's a lot of easy points. This strategy should allow you to easily earn a Platinum rating.

After completing that mini-game, head right along the screen toward higher ground. When you ascend to that ledge, there will be some dialog and then the mission is complete.
